6l4 STRATrORAPIlICAL GKOI.OOy. 



sicnilc. No observations liavc been taken between this road and Saddle- 

 back niounl:iin, in Noilliwood. Iktween the two vilkif^es of Dcerficld is 

 a coarse mica schist, of the kind associated with the gneiss. The north- 

 ern boundary of the latter rock is irre^^ular throii{;h this town. Granitic 

 gneiss hummocks abound east of the ('entre, dip north-west. At the 

 cemetery, sf)uth of S. V. Rollins's, the dip is north-west. The same at 

 the brook a mile south. The north-west part of Raymond belongs to the 

 gneiss. The boundary line between it and the mica schists may be 

 drawn from the south end of I'awtuckaway to a little below Jones's pond, 

 and then direct to Massrd)csic lake. At C. G. Smith's, near the north 

 line of l\.aymond, the dip is north-west ; as also in the south-west part of 

 Nottingham. From Jones's pond to the west line of Candia the rock is 

 the twisted gneiss of Manchester, and there is a synclinrd axis in the east 

 part of Candia, followed by a very marked anticlinal in the central part of 

 the town. A short distance north of the depot is the south-east dip; but 

 it is lo the north-west at Candia village. The axis has not been traced 

 farther to llic north-east. Its course, as mentioned on a previous page 

 (560), would, if continued, proceed to the sicnitic eiuptive mass of the 

 I'awtuckaway mountains. The south-east jiart of Candia contains many 

 gneiss ledges, particularly on T'atten's hill. Rattlesnake hill, in Raymond, 

 is of this materia], and may be an isolated fragment. There is a similar 

 one of unknown extent near D. liall's, in the south-east part of Auburn. 



There is a small area of gneiss in the north part of Chester, consti- 

 tuting a large hill. 'J'he strike is N. 55" K. in the south j)art of it, and 

 the dip N. 30° W. on the summit. It crosses the road near a school- 

 house, more than a mile west of the village. We find the same rock 

 farther north-east, bolli in Clicslcr and RaynK)nd, but it does not seem to 

 connect with the West J^i)ping exposures. The latter crop out by the mills 

 on the Lamprey river in vertical strata, with the course north-cast and 

 south-west. A large number of loose blocks of this gneiss are spread over 

 the plain near the station. Drift covers the natural continuation of the 

 range in the south part of l'>pi)ing and the north part of JM-emont; but it 

 appears near D. Rowc's, west of the village, and in the south-west part of 

 the town dips S. 75° E. These observations indicate the anticlinal struct- 

 ure in this area. The town of Sandown has not been explored yet, so that 

 the representation upon the map is based only upon probabilities. The
